【摘要】 近红外光辐射医学成像研究已经愈来愈受到重视。光学成像法与现有的辐射成像方法相比具有辐射是非电离的；可以区分软组织；能够得到组织体功能信息等优点，因此光学医学成像法可作为连续成像的检测仪器应用在乳癌诊断、新生儿脑部含氧或缺氧分析、成人组织功能的检测等医学领域。本文综述了近红外光辐射医学成像研究的实验技术之一 直接成像法更多还原

【Abstract】 Optical computerized tomography (OCT) based on near infrared (NIR) radiation has been under intensive development.OCT has many advantages over other existing medical modalities,including use of non ionizing radiation,display of contrast between soft tissues and disclosure of functional information. Its clinical application are safe and more effective for the detection of breast diseases,a means of imaging cerebral oxygention and function in the human neonate and the study of evoked responses in both adults and infants.In this paper we review the direct experimental methods proposed and the merits and limitations are discussed.更多还原
